Description
Technical Field
The invention belongs to the technical field of metal material surface treatment, and relates to a zinc-aluminum-magnesium coating steel plate passivation solution for preparing a black passivation film with excellent corrosion resistance on the coating surface.
Background
The improvement of corrosion resistance is a major goal continuously pursued by the plated steel sheet. With the increasing demand of the user market for corrosion resistance of materials, hot-dip Galvanized (GI) and hot-dip 55-Zn alloy coated (GL) steel sheets, which are widely used in the industries of construction, automobile, home appliance manufacturing, and the like in various countries around the world, have been "conventional" coated steel sheets, and users are expecting to develop coated steel sheets having better performance. The hot dip coating Zn-Al-Mg alloy coating steel plate is a novel coating steel plate produced by the method.
The Zn-Al-Mg alloy coating has attracted wide attention abroad in the 80 s of the 20 th century, and becomes a research focus in the professional fields of hot dip galvanizing and zinc alloy coating. From the research results of the same lines at home and abroad, the hot-dip galvanized Zn-Al-Mg alloy coated steel plate added with Mg has better corrosion resistance under the condition that the contents of Zn and Al of the coatings are at the same level, and the processing application performance (formability, weldability and paintability) of the material is excellent, so that the hot-dip galvanized Zn-Al-Mg alloy coated steel plate can replace the existing corresponding hot-dip galvanized or zinc alloy coated steel plate, and has very wide market demand prospect.
Because a large amount of Al and Mg elements exist on the surface of the zinc-aluminum-magnesium alloy coating, the oxidation and corrosion phenomena are easy to occur in the processes of placement, storage and transportation. In order to improve the corrosion resistance of the zinc-aluminum-magnesium alloy coating steel plate, surface passivation treatment is required. With the improvement of life quality and the enhancement of national comprehensive national force, people have higher and higher requirements on the aesthetic property of materials and the environmental protection property and performance of materials, and a Zn-Al-Mg black passivation plate is developed in Japan and provides wider application space in the fields of electric appliances, buildings (such as guardrails), automobiles and the like. China has developed a zinc-aluminum-magnesium plated steel plate later, research on the black surface of a zinc-aluminum-magnesium plated layer has not been carried out yet, and the gap between the black surface and the national technology of Japan and the like is large.
The prior patents mainly and intensively report black treatment methods for zinc plating, zinc alloy plating or steel surface, and the black surface treatment of zinc-aluminum-magnesium plating is less reported. Patent CN 101876071A provides a chromium-free and silver-free zinc-plating black passivation solution and a preparation method thereof, which comprises the following components: 10-20g/L of film-forming agent silicate, 20-30g/L of blackening agent nickel sulfate or copper sulfate, 1-3g/L of auxiliary film-forming agent sodium acetate, 3-7ml/L of PH regulator sodium hydroxide or sulfuric acid, and the balance of deionized water. And pickling the galvanized part, soaking the pickled galvanized part into the silicate black passivator for 1-2min, taking out the galvanized part, and washing the galvanized part with water to prepare the black galvanized part. The passivation solution provided by the invention is low in cost, environment-friendly and efficient, the black galvanized passivation film is compact and wear-resistant, and the service life of the material is prolonged. However, the method for producing black galvanized steel is suitable for parts with smaller volume and is not suitable for continuous production of strip steel.
Japanese patent No. 104246014A provides a method for manufacturing a black-plated steel sheet and a method for manufacturing a molded body of a black-plated steel sheet. A zinc-aluminum-magnesium-plated steel sheet, which comprises 0.1 to 22% of Al,0.1 to 1.5% of Mg and the balance of Zn, and has a plating thickness of less than 100 μm, is used as a substrate. The steel plate is placed in a closed container with oxygen content below 13% and water vapor temperature of 100-350 deg.C for 2-24h, and inert gases Ar and N are introduced into the steel plate to treat the steel plate 2 He, etc. The prepared black plating layer has excellent processing performance and strong corrosivity, and the preparation method is environment-friendly and nontoxic, and meets the requirements of the fields of building roofs, packaging, automobile and household appliances and the like on steel plates with black appearances. However, the method of steam oxidation has low production efficiency, long production time, large energy consumption and high cost, and can not continuously produce the zinc-aluminum-magnesium coating strip steel with black surface on line.
Patent CN 102757724A provides a preparation method of black antirust UV paint for a petroleum steel pipe, and the UV paint comprises 20-22% of film-forming agent acrylate, 20-25% of cross-linking agent hyperbranched polyurethane acrylate, 4% of adhesion promoter Pasteur LR8956, 4.5% of photoinitiator 651ITX, 1% of black carbon powder, 100.5% of leveling agent TEGO Glide, 0.5% of defoaming agent BYK088, and 0.5% of dispersant BYK 2008.
